Two heating areas design in which upside heating area is designed with hot air, downside area is designed infrared heating. All heating areas could be controlled separately which are equipped with high precision temperature controlling meters. This product can be configured with eight grades of heating or cooling temperatures and store ten sets of temperature configurations in which external temperature testing terminal equipped to adjust every parameter on time. Designed with K-type thermocouple and automatically temperature offset system which is combined with temperature controlling module to control temperature accurately with difference in 2°C, and achieve precision analysis and correctness. V-type slot design for PCB board to position fast, accurately and conveniently which meets the requirements of various PCB board layouts and positioning. Flexible and mobile universal clamp can protect PCB, avoid damage to PCB edge component, avoid distortion to PCB and suitable for reworking of various BGA packaging size. Equipped with various nozzles which could be rotated for 360° to be convenient for installation and replacement. Eight grades of heating, cooling and constant temperature control. Alarming function as desoldering or soldering work completed to prompt operator ready for next procedure. At the same time, automatic or manual enabled high, horizontal air flow fan will be used to cool PCB down before its distortion, to retain soldering works. Approved by CE certification and equipped with automatic cut-out.
